Hi Everyone this will be my first Ducted Fan JET, so its going to be fun to try something New, it will be a profile Jet, with a 6MM wing and 9MM fuselage, the wing and fuselage only weight 2oz, the EDF is an E Bay Special , I think a 3 cell 1300mah 20C lipo should push it, it will have elevons and throttle, its a 3 channel ,Take care, Chellie

The PINK is on the Way LOL

CHELLIE

I was trying out the motor, and found out it does not like a 25Amp ESC, at 3/4 throttle it quits and gets hot after a short burst, Ok so I tried a 30 Amp ESC, same thing Ok proccess of elimination, I tried a 40 Amp ESC It Likes That Better It get a little warm, so does the lipo at WOT, but, I dont think I will be running it at WOT for very long, just in short burst, as it puts out a lot of thrust, I was Amazed I think I will have to be careful here, as to not tear off the wing Yes you guessed it, I dont have a Wattmeter yet, its on Order its the Watts up meter, soon, as I do need it, this motor is really gulping the amps, I would not be surprised to see 600Watts Take care, Chellie

CHELLIE

Hi Mike and thank you for the complement yes i will draw up some plans when its done, its an easy build, the wing span is 30 inches the fuselage is about 20" I epoxied a piece of 1/8" X 1/4" x 18" basswood under the fuselage to give it some strength, and to act as a skid, its coming along nice, I will Maiden it this weekend, I hope everything goes well I can see that this jet is going to move Fast, the EDF has a lot of thrust to it take care, Chellie

CHELLIE

Yes, Pink and gold do go good together I will have to try it, Take care, Chellie

CHELLIE

thank you James, I see you have taken on quite an undertaking, beautiful plane, I like it, Take care, Chellie

Me too Jim It should be fun, I am using the wing dimentions from my pink pusher jet, and made a fuselage for it with the rudder, it will be an interesting plane to fly, I just have to figure out where the CG is going to be at Take care, Chellie

CHELLIE

Hi Dr Kiwi yes I found that out I think I will have to use a 1800mah 20C 3 cell lipo at least that It does get hot real quick, 5300KV is a lot,
I dont think i will be able to fly it WOT, it has a lot of thrust, the Plane and motor just weigh 6 oz, I will check every thing with a watt meter, even the 40 amp ESC gets pretty Warm at WOT new Watts up meter on Order, Yea , getting into these high amp consuming motors, has forced me into getting a wattmeter, where before I was able to use test charts on different motors, and have a good idea on amp usage, Take care, Chellie

CHELLIE

Hi Larry yes its going to be Elevons, I dont think I will be able to use my 1300mah 20C lipos, the EDF draws a lot of Amps, I think I will need a 1800mah 3 cell 20C lipo or more , Take care, Chellie

CHELLIE

Hi Everyone here are a few more pics, I got a little more done, I added some 1/8" x 1/4" bass wood on the bottom, for strength and a skid, just needs the electronics installed, it weighs 6oz at this point Take care, Chellie

BTW I Trimed it in Pink, Because I know How Much Larry Likes Pink Just for you Larry

CHELLIE

I need to get some gold monokote trim tape, I only had silver, so I used it but gold would look very nice too, Take care, Chellie

CHELLIE

Thank You John

CHELLIE

Yes I agree with you I will look at a CG calculator to get an Idea, Take care, Chellie

the wing is 30" L x 12" at center x 4" tip

CHELLIE

Its DONE, Yea, Just have to maiden it now, I had to use a 2250mah 20C 3cell lipo to get the CG, and I tried to make it as Slippery as possible for a profile Jet, notice the air deflectors on front of the lipo and the servos, I also tried to enclose the wiring as much as possible, with a cover. on the top of the wing from the nose to the wing, I added a piece of Bamboo, to help to give the nose some strength, it helped, just incase of a hard landing , I gave the EDF about 1 to 2 degrees of down thrust, as I found out that these flat wings, seem to like to have a little load on the wing, to help stabilize them, at faster speeds, the motor and esc seem to like the 2250mah 20C 3 cell, as the motor and ESC get very warm, but not hot, at least i can hold them in my hand , maybe tomorrow i will give it a test flight Yes I will have Butterflies in my stomach, every maiden flight, that seems to happen for some reason, Take care, Chellie

CHELLIE

Thank you Larry

Thank you GreenAce

CHELLIE

Hi Everyone It Flies Great Steve flew it, Ray Lanched it and I Videoed the flight, SWEET SWEET SWEET very solid flyer, its as fast as a Stryker, handels very well, and maked a nice screaming sound as it goes by I am very happy with this little Jet, here is a video of its Maiden Flight, Enjoy, Chellie

CHELLIE

Thank You GreenAce I have built some planes that are Ify, if they will fly or not, I have a triplane that I have not maiden yet, I think it might be a little on the Heavy side, but i am going to try to fly it anyway if it does not fly, then it will just hang from the celing to collect dust Take care, Chellie

CHELLIE

LOL I dont know if it puts out 600 watts or not, but the way it was eatting amp, I bet it up there I ordered a watts up meter, i really do need one, Take care, Chellie

CHELLIE

Hi Frank Thank you for the Complement I have been Involved in Model Aviation for a long time & have learned a lot over the years, what I have learned goes into my builds, E Power is rather new to me, as I have been a nitro flyer for a long time, I am still learning E Power systems, and Having fun doing it Good Luck to you on your Build, and Lets Race soon for DRINKS Take care, Chellie

CHELLIE

Thank you Larry Thats Quite a Complement coming from you the flying field was not all that big, so you have to get off the throttle quick, I will do a speed run at the fair grounds, its longer, and have you doppler it for me, thank you for trying, Take care, Chellie

CHELLIE

Thank You Jim for the Complement It was a fun build, and it flys great, I am very happy with it, Take care, Chellie

CHELLIE

Hi herk I sanded the EDF housing here it meets the foam at and epoxied the EDF in place, the fuselage is 9MM foam, its thick, so there is a good bond there, i gave the EDF about 1 to 2 degrees of down thrust, THE EDF WILL POINT UP A BIT, to force the wing down, to load the wing a bit, I have found that a little down thrust on a flat foam wing , helps alot to stabilize a profile plane, if you dont have any 9MM foam, glue 2 pieces of 6MM depron together for the fuselage, hope that helps, Chellie

CHELLIE

It was Screaming great, I think I have to advance the timing on the ESC, it was sputtering a little at WOT, or maybe the fuel mixture was a little lean I let Steve fly it, because he is one of the best pilots in our group, and I wanted to Video the flight, the rifle stock works great in trying to video the plane, as you dont have to try to keep the plane in the view finder, just sight the camera, with the open sites, adjust the zoom, and aim with the open sites, here is a build on the rifle stock camera holder, take care, Chellie

Thank you Rick it was fun watching it fly for the first time it sure makes a lot of noise too Take care, Chellie
